HOUSTON, Texas – HOUSTON, Texas (KTRK) – While you were sleeping, a computer network problem caused problems for at least three airlines.
Southwest, Delta and Alaska Airlines have been affected.
The problem prevented airlines from receiving the weather information needed to operate flights.
According to flight tracking site Flight Radar 24, more than a dozen Southwest Airlines flights scheduled to take off on Monday had either not departed or had been delayed.
Southwest Airlines says operations are resuming and is working to get passengers to their destinations.
A quick check of flights at Hobby Airport early Tuesday morning showed most flights were on time.
Delta and Alaska Airlines said the issue was affecting their booking sites and apps.
Delta sent ABC News the following statement on Monday evening:
“Delta teams are working to quickly resolve a technical issue that makes it difficult for customers to purchase flights on delta.com, the Fly Delta app and through our reservations call center. Check-in for flights is not affected. We apologize to our customers for any inconvenience this may cause. “
